jQuery Regular Expression Help

Saw a challenge on Twitter so I've been working my way through it, granted I am not the best with Regular Expressions. This is what I have so far:

var pass_regex = new RegExp(/^[a-z][A-Z][0-9]|[!@#$%^&*()_]+$/);

I am trying to match a password input that contains:

  • 1 Lowercase Letter
  • 1 Uppercase Letter
  • 1 Digit OR Special Character

Where I am getting stuck is on the 'OR' part, I thought the pipe separator between [0-9] and my set of special characters would work but it doesn't seem to.

Any ideas?

I think it decodes like this: (starts with one lowercase letter, followed by one uppercase letter, ending in an uppercase letter) OR ( one or more special case letters)

sR7 would match, and #@#%$#$ would also match

'^' - means the string starts with '$' - means the string ends with '+' - means one or more characters

I like to use the http://rubular.com/ website to test out regular expressions. You can copy your expression over to the site and create test strings and see which ones match.
